Before describing the tank liner 100 and the water heater provided by the present invention, a brief description will be given of names appearing in the following text.
Thermal shrinkage and cold expansion material: the thermal shrinkage and expansion material refers to a negative thermal expansion material with a linear expansion coefficient or a bulk expansion coefficient of a negative value in a certain temperature range. There are various kinds of heat-shrinkable and cold-swellable materials, such as antimony-copper memory alloy, pyrophosphate compound or pyrotungstate compound. Alternatively, the heat-shrinkable and cold-swellable material of the present invention adopts Cu 1.8Co0.2V2O7 or Zn 1.6Mg0.4P2O7.
Wherein, for Zn 1.6Mg0.4P2O7, the linear expansion coefficient can reach negative thermal expansion exceeding-60 ppm/. Degree.C in the temperature range of-10-80 ℃ including room temperature. The water temperature range in the inner container of the water heater is approximately 10-75 ℃, and the heat shrinkage and expansion material Zn 1.6Mg0.4P2O7 can meet the negative thermal expansion characteristic in the use temperature area of the water heater. Zn 1.6Mg0.4P2O7 can be obtained by synthesizing zinc pyrophosphate (Zn 2P2O7) with magnesium pyrophosphate (Mg 2P2O7) exhibiting negative thermal expansion characteristics at 68 ℃. It can be seen that Zn 1.6Mg0.4P2O7 is an oxide composed of zinc (Zn), magnesium (Mg), phosphorus (P) as main components, has advantages of low cost, environmental friendliness, and the like, and can be easily synthesized by a general solid phase reaction without using a high-cost synthesis method such as high-pressure or vacuum packaging.
Fig. 1 illustrates a structure of a tank liner 100 provided according to an exemplary embodiment of the present invention.
As shown in fig. 1, the tank liner 100 includes a liner body 10 and an air bladder 20 provided in a receiving chamber of the liner body 10, the air bladder 20 being filled with a heat-shrinkable and cold-expandable material (not shown). When the temperature in the accommodating chamber of the liner body 10 increases, the heat-shrinkable and cold-expandable material shrinks, so that the occupied space of the air bag 20 in the accommodating chamber of the liner body 10 is reduced, and when the temperature in the accommodating chamber of the liner body 10 decreases, the heat-shrinkable and cold-expandable material expands, so that the occupied space of the air bag 20 in the accommodating chamber of the liner body 10 is increased.
In some embodiments, the liner body 10 is connected with a water inlet pipe and a water outlet pipe, and a safety valve is arranged on the water inlet pipe. When the water pressure in the liner body 10 increases, a certain amount of water can be discharged to the outside of the liner body 10 through the safety valve. The water inlet pipe is connected to a tap water pipeline in the home of a user, so that the water inlet pipe is communicated with external cold water. The outlet pipe is connected with a bathroom shower head, a kitchen faucet and the like, so that hot water of the outlet pipe can flow out to the outside and is used for providing hot water for users.
Specifically, before using the water heater, tap water in the user's home is introduced into the receiving chamber of the liner body 10 through the water inlet pipe. At this time, the water temperature in the accommodating chamber is low, approximately at room temperature, and the heat shrinkage and expansion material in the air bag 20 expands, so that the air bag 20 occupies a part of the space of the accommodating chamber of the liner body 10. When a user uses the water heater, the heating pipe 11 in the liner body 10 is electrified, the water temperature in the accommodating chamber of the liner body 10 is gradually increased, the thermal shrinkage and expansion material in the air bag 20 is shrunk, the occupied space of the air bag 20 in the accommodating chamber of the liner body 10 is reduced, the space capable of accommodating heated and expanded hot water is released, the pressure brought to the liner body 10 by the increase of the water temperature is relieved, and the purposes of balancing the pressure of the liner body 10 and reducing the water dripping amount of the safety valve are achieved.
In some embodiments, the liner body 10 includes a liner middle barrel, a first seal head and a second seal head, wherein openings are formed at two ends of the liner middle barrel, the first seal head covers one end opening of the liner middle barrel, the second seal head covers the other end opening of the liner middle barrel, and a containing chamber for storing water is formed by surrounding the liner middle barrel, the first seal head and the second seal head. Optionally, the water inlet pipe and the water outlet pipe are integrally formed with the inner container middle barrel, so that the water inlet pipe and the water outlet pipe are welded to the inner container middle barrel in a welding mode, welding slag or poor welding technical problems can not be generated, and potential safety hazards are avoided.
It should be noted that the tank liner 100 may be a non-metal liner, a stainless steel metal liner or an enamel liner, which are commonly used in the art, and the present invention is not limited thereto.
In addition, the heating pipe 11 in the liner body 10 comprises a top layer heating pipe 111 and a bottom layer heating pipe 112, heating pipe cold needles and heating wires are arranged inside the top layer heating pipe 111 and the bottom layer heating pipe 112, and the top layer heating pipe 111 and the bottom layer heating pipe 112 are both arranged on the first sealing head or the second sealing head.
Optionally, the bottom heating pipe 112 is bent in a zigzag shape, and the tail end of the pipe body is bent in a hook shape; the top heating tube 111 includes a non-heating portion and a heating portion connected to a distal end of the non-heating portion, where the non-heating portion is disposed parallel to the bottom heating tube 112 and the distal end is bent upward. The heating part is spiral and surrounds the periphery of the water outlet pipe of the inner container. The heating part and the non-heating part are integrated by laser butt welding. The heating pipe cold needles in the top layer heating pipe 111 penetrate through the non-heating part, and the heating wires in the top layer heating pipe 111 penetrate through the heating part.
In some embodiments, as shown in fig. 2 and 3, a supporting frame 30 for fixing the airbag 20 is provided in the container body 10 accommodating chamber. The supporting frame 30 provides an installation space and a position for the air bag 20, and can limit the displacement of the air bag 20 during deformation, so as to prevent the air bag 20 from being burnt out due to contact with a heating pipe arranged in the liner body 10.
As an example, as shown in fig. 4, the airbag 20 includes a flexible bladder 21, a flange cover assembly 22, and a plug 24. The flexible bag 21 has a bag-like or tubular structure with an opening, and the heat-shrinkable and cold-expandable material can be filled into the flexible bag 21 through the opening. The opening of the flexible bag body 21 is provided with a flange, and the flange cover assembly 22 is fixedly connected with the support frame 30 after being in sealing connection with the flange, so as to fix the flexible bag body 21.
The flange cover assembly 22 is provided with an inlet 23 corresponding to the opening of the flexible bag 21, and a heat-shrinkable and cold-expandable material can be filled into the flexible bag 21 through the inlet 23. After the filling of the heat-shrinkable and cold-swellable material is completed, the filling opening 23 is sealed by a plug 24 to prevent the heat-shrinkable and cold-swellable material in the flexible bladder 21 from flowing out.
Alternatively, the flexible bladder 21 is made of a rubber material, and has a certain elasticity, and can be deformed along with the shrinkage and expansion of the heat-shrinkable and cold-expandable material. As an example, the flexible bladder 21 may be a heat-resistant member such as a fluororubber member or a silicone rubber member, and is suitable for a working environment with a high water temperature of 75 to 80 ℃ for a long period of time.
In addition, the size of the flexible bladder 21 and the filling amount of the heat-shrinkable and cold-swellable material may be determined according to the maximum capacity of the liner body 10, and the present invention is not limited thereto.
In some embodiments, the flange cover assembly 22 includes a front flange cover and a rear flange cover; the front flange cover and the rear flange cover are fixedly connected with the support frame 30 after the folded edges are clamped between the front flange cover and the rear flange cover. Specifically, the front flange cover has an annular structure, the front flange cover passes through the flexible bag body 21 and is positioned at the front side of the folded edge, the rear flange cover is positioned at the rear side of the folded edge, and the front flange cover and the rear flange cover clamp the folded edge of the flexible bag body 21 and then are fixedly connected with the support frame 30 in a sealing manner by using the fastener 33. The fastener 33 may be a hexagonal screw or other connection structure commonly used in the art, which is not limited in the present invention.
It should be noted that, the front flange cover, the rear flange cover, the plug 24, the support frame 30, the fastener 33, and the like should be made of non-metal or stainless steel or be installed in the accommodating chamber of the liner body 10 after being subjected to rust-proof treatment.
In some embodiments, as shown in fig. 6, the support bracket 30 includes a housing 31 and an end cap 32. The shell 31 is covered on the outer side of the flexible bag body 21, and the non-bearing part of the shell 31 is provided with a water permeable hole 311, so that water in the liner body 10 can flow conveniently, and the heat shrinkage and expansion material in the flexible bag body 21 can sense the change of the water temperature. The end cover 32 is disposed at one end of the housing 31, and the end cover 32 is fixedly connected with the flange cover assembly 22 and the inner wall of the liner.
Note that, the non-load-bearing portion of the casing 31 refers to a portion located above and/or on both sides of the flexible bladder 21, and a portion of the casing 31 located below the flexible bladder 21, that is, a load-bearing portion of the casing 31, is to bear the weight of the heat-shrinkable and cold-expandable material in the flexible bladder 21, so that the water permeable hole 311 should not be formed in the casing 31, as shown in fig. 2, so as not to allow the flexible bladder 21 to be embedded in the water permeable hole.
In addition, in order to satisfy the strength of the support frame 30, as many water permeable holes 311 as possible may be provided in the non-load-bearing portion of the housing 31. The shape of the water permeable hole 311 may be circular, quincuncial, rectangular, etc. The size of the water permeable hole 311 may be varied according to the actual situation, and the present invention is not limited thereto.
In addition, the side of the housing 31 opposite the end cap 32 may not be provided with the end cap 32, facilitating the installation of the airbag 20 and the support frame 30.
In some embodiments, as shown in fig. 5, the filling port 23 is connected to a filling short pipe 231, and the end cover 32 is provided with a relief hole 321 corresponding to the filling short pipe 231; the filling short pipe 231 passes through the avoiding hole 321 and is connected with the plug 24 in a sealing way. The heat-shrinkable and cold-swellable material can be replaced without removing the air bag 20 from the support frame 30, thereby facilitating the maintenance and repair of the water tank liner 100.
By way of example, the fill neck 231 is a threaded tube and the plug 24 is a threaded cap that is sealingly connected to the threaded tube. The diameter of the threaded pipe is approximately 5-10 mm.
The invention also provides a water heater which comprises a shell and the water tank liner 100. One or more of the above-described water tank liners 100 are disposed within the housing to form a multi-liner water heater.
The heat-shrinkable and cold-expandable material filled in the air bag 20 in the water tank liner 100 shrinks along with the rise of the water temperature of the water heater liner, releases a certain space to accommodate the expansion amount of hot water, balances the pressure of the liner, reduces the leakage water dropping amount of the safety valve, and does not need additional operation when in use by a user. Moreover, the balance of the liner pressure can also improve the service life of the water heater, reduce the water dripping amount of the safety valve, play a role in saving water, ensure that users do not need to worry about the water dripping of the safety valve any more, and greatly improve the user experience.
In addition, the air bag 20 is arranged in the water tank liner 100, so that the occupied space of the whole water heater in the home of a user can be reduced, and the attractiveness of the water heater can be improved.
The water heater can be an electric water heater or a solar water heater.
